Water Samplers

RS-485 Options

• When sampling hydrocarbons, grease, oil, etc., regular cleaning of the meter-

ing chamber, volume control tube, liquid detect/conductivity rod, and intake

ow tubing is essential to continuous successful sampling.

• Placing the end of the intake tubing directly on sand and gravel beds can

result in unrepresentatively high sediment loads being collected. If a strainer

is not used, gravel and sand may lodge in and plug the intake tube, metering

chamber, and sampler distribution body (discrete sampler only).

• Connecting the battery cables improperly will cause the PVS5120 fuses to

blow in order to protect the PVS5120. Replace them with the same rated

fuses as the originals. (28314-5A, 28315-10A)

• Before deploying, check all connections, intake tubing, vacuum tubing, and

the meter chamber cover for proper tightness and seating to prevent air

leakage.

• Exercise proper lifting techniques when hefting this product.

• Damages caused by freezing conditions will not be covered by the warranty.

• When the PVS5120 is being stored for periods of time, disconnect the battery

to reduce discharge over time.

Caution!

Required Gear

• Sampler (top, control section, base with bottles)

• 7/8” wrench (adjusting rods)

• 9/16” wrench (adjusting rods)

• 5/32” Allen wrench (adjusting rods)

• Small Flat head screw driver (wiring to PVS5120)

• USB cable (connecting to VSC100)

• Control cable (connects datalogger to sampler)

• 12V Battery

• External power cable (only if using an external battery)

• Datalogger with its own power supply, protected in an enclosure if necessary

• MD485 and cable (SC12 serial cable)

• 3/8” Hose clamp to connect intake hose to the sampler

• Laptop Computer with Device Conguration Utility (DevCong 2.09 or higher)

• 1/4” nut driver (to tighten hose clamps)

• If using an external battery, make sure the external power cable (Fig. 1D) is

stripped and the correct leads are in place to connect to the battery. Connect

the external power cable to the front of the sampler (Fig 2).

• Connect the yellow caps around the fuse.

5. Turn on the sampler and set the 3-way switch on the control panel to the power

source being used (Fig. 2). If powered correctly, the green indicator light (Fig. 2) will

come on for several seconds, and then start blinking green once per second.

6. Connect the intake hose and tighten the hose clamp.

7. Put the sinker end of the intake hose into the water body to be sampled, ensuring at

least 3 inch depth.

8. Run the Autodeploy routine by pushing and holding the manual control button until

the sampler begins running (hold the button shown in Fig. 2 and 3 for approximately

5 seconds). The Autodeploy routine will set the purge and vacuum times based on

the length of the hose and the change in height between the sampler and the water

source. Wait for the sampler to stop before proceeeding to Step 9.

9. Remove the control section of the sampler and empty the sample just collected.

10. Push the Manual Control button ONCE (Figs. 2 and 3). This will “service the

Refer to Figure 1a.

1. Loosen the brass nut to set the volume control tube to the approximate volume re-

quired for collection. Align the base of the tube with the desired graduated marking

on the metering chamber. It is best to collect this volume at least once to make sure it

matches expectations. If necessary, adjust the tube up or down to obtain the desired

collection volume.

2. Set the height of the conductivity rod. The bottom of the conductivity rod must be

higher in the metering chamber than the volume control tube (at least 1/2”), but

below the bottom of the oat valve barrier.

3. Connect the positive lead to the top of the conductivity rod (yellow cap).

4. Connect the battery.

• If using an internal battery, place it in the mount and connect the red and black

leads to the matching terminals.
